B0.0KHOLDER..

i Application filed, June 24, 1921, Serial My invention relates to newand useful improvements in a book holder and more particularly to adevice of this character adapted for a telephone book or other d1-rectory! to which, frequent reference is made.

The primary object 01'' the invention r esides in the construction ofthe holder 111 such a manner that it will normally hold the book invertical position against a desk, wall, or other supporting object, butwh ch may be swung and raised so as to support the bookin open.horizontal position.

Another object consists in the provision of means for securelysupporting the holder in raised position and for quickly releasing thesupporting means to allow the holder to drop into its original orvertical position.

A further object resides in a novel form of wing for opening, closingand supporting thebook carried by the holder, said wings beingdetachable so that they may be removed when desired for shipping or forreplacing should they become broken.

With the above and other objects in view,

which will appear as the description proceeds, my invention consists ofthe novel details of construction and arrangement of parts, describedand illustrated; in the fol lowing specification and drawings, and while1" have illustrated and described the preferred embodiments of theinvention, it will be understood that such changes may be made as willfallrwithin the scope of the appended claims.

fastening means and, as more clearly, shown in Figure 1, preferably isformed to extend at an angle so as to take up the least possible space.A frame is. pivotally connected' to the arm 1 by' means of the pin, 4,said pin having ared'uced portion 5adapted to extend through the sleeve2. and a further reduced" portion 6- adapted to pass through an openingin the lower rearwardly extending arm 7 of the frame. A. thumb screw 8has its threadedportion 9-extendin-g through an opening in the upperrearwardly extending arm 10 of the framemnd entering a recess formedinthe upper end of the pin 1. By the construction described, it will beseen that the frame?) is carried by the arm 1 so as to freely swinghorizontally and while 1' have shown the frame as formed of twosubstantially C-shaped portions, connected together, it will beunderstood that it i'i'iight equally as well be constructedin one piece.

A. support 11 is connected to the frame 3, by thepin 12, said supportbeing mounted for horizontal swinging movement and for verticaladjustment. The pin. 12 passes through openings formed in the upper andlower forwardly extending arms 13 and 14: ot'the trame and lugs 15.formed on the rear ace; of the support 11. Vertically spaced pro ections16 are formed on or secured to the rear face of the support 11, as moreclearly shown in- Figures 1 and 2, of the drawings. These projections 16are used for vertically adjusting the support 11 with respect to theframe Normally, both projections will be positioned between the arms 13and 14 of the frame, but if it is desired to raise the support, with itsassociated parts, the projections will be positioned as shown inFigs. 1andv 2, with the upper projection; engaging the top of the arm 13, thelower projection limiting the movement of the support when the book-rest21, to be later described, is raised. The raising of the support, 11 issometimesnecessitated by unusuallythick desk tops and by providing; theprojection 16,. allowing; the vertical adjust: ment of the support,theleaf supports, to be later described, will clear the topof the desk,when opened, allowing the bookto be swung around to the user withoutstriking the desk. The horizontal swinging movement of the support is:limited by the end of the arm. 13 contacting with} the; rear face of thesupport. The support 11 is formed with the side flanges 17 and at thetop the flanges have the forwardly extending portions 18. "Outwardlycurved or flared lips 19 are formed on the upper edges of the portions18 for a purpose to be later described. Pivotally connected to theportions 18, of the support 11, by means of a horizontally extending pin20 is a book-rest 21 having the lower end rearwardly curved to providethe handle or gripping portion 22. The horizontal pivot pin 20allows thebookrest to be raised vertically "and to be extended in a horizontalposition to support the book in a manner to belater described. A bar 23is pivotally connected adjacent the lower end of the support 11 by thehorizon.-

tally extending pin 24, the pivoted end of the said bar being receivedbetween the sides 7 17. Vl hen the book-rest is lowered .intoverticalposition the bar 28 will also assume a substantially vertical positionas more clearly shown in Figures 1 and 2 of the drawings. 'Verticallyspaced angle iron plates or-brackets 25-are secured to the rear face erthe book-rest 21 and rotatably support, therebetween, a rod 26 havingthe notches 27 intermediate the ends thereof. The rod 26 is normallypositioned, by the coiled spring 28, to have the notches 27 in positionto be engaged by the lower edge 29 of the bar 23, or in, other words thenotches will normally facetowards the rear. The coiled spring 28surrounds the rod 26 adjacent the upper end and one end thereof isconnected to the uppermost angle iron bracket 25 and the opposite end isconnected to the rod so that when the rod is rotated by the lever .30,extending through the hori zontal slot 31in the book-rest 21, it will beplaced under tension to return the rod to its original. position whenthe lever is released. Pivotally connected adjacent the lower end of thebar 23, by the pin 32 is the yoke which surrounds the 'rod'26 in such amanner that the edge 29 of the bar will contact with and ride on therod. The edge of the bar is held tightly against the rod by theleafspring 34 received between-the rod and face of the yoke as more clearlyillustrated in Figs. '2 and 8. lVhen the yoke is slid upwardly on therod the spring will cause the edge of the bar to engage the notches 27and thereby hold the book-rest in an inclined or horizontal position.

A" red 35 is provided for connecting the book, not shown, to the bookrest. The lower end of the rod is bent at right angles and is providedwith an enlarged end 36 of greater diameter than c the opening 37through which the right angle portion of the rod passes. The upper endof the rod is also bent at right angles and passes through the opening38 and is screw threaded, as shown at 39, to receive the thumb nut 40,It will be understood that the rod 35 is vplaced be tween the leaves ofthe book and tightened by the thumb nut 40. The rod will be con nectedto the book rest by first inserting. the threaded end 39 through theopening 37 and then through the opening 38.

A pair of vertically spaced eyes 41 are formed on or secured to eachside edge of the book rest 21 for pivotally connecting the wings 42 tothe book rest. The wings 42 are formed with the lower reduced extensions43 adapted to, be received in the lowermost eyes 41 and the reducedextensions 44 adapted to be received in the uppermost eyes 41.' Theupper ends of the extensions 44 are bent at an angle, as shown at 45, toengage behind the lips 19 as more clearly shown in Figures 1, 3 and .4of the draw ings. The wings are swung by the angular extensions 45engaging with thesaid lips as the book rest is raised and lowered and itwill be understood that the wings engage the outer faces of the book.,When the book rest is in a vertical position, the book will be heldclosed but when raised to horizontal position the wings will also assumea horizontal position and support the book in open position. Coiledsprings 46 encircle the extensions 44 of the wings between the shoulders47 and upper eyes'41 and these springs hold the wings in proper positionwith respect to the eyes, at the same time allowing the wingsto bedisconnected when desired. Plates 48 are secured to'the rear edge of thewings and when the wings are in horizontal position will engage theedges of the book rest, as more particularly shown in Figures 3 and 6,and support the wings. Ears 49 are struck from the book rest, adjacentthe rod end and engage the lower end of the book to help support thesame. 7

From the above detail description it is thought that the constructionand operation of my book holder will be clearly understood and it willbe seen that I have provided a device, as previously stated,particularly adapted for normally holding; a boolrin vertical positionagainst a desk, wall, or other support,l)ut which may be raised to openand support the book'in horizontal position forreference. The arm 1extending at anangle, from the support, takes up little room and allowsthe frame 3 to be swung against the support with the book rest extendingvertically, with the book closed, and parallel with the support. When itis desired to refer to the book the frame 3 is swung horizontally awayfrom the support and the handle 22 of the book rest,'is grasped and thebook rest raised vertically. The raising of the book rest will slidetheyoke 33 on the rod 26 and the edge 29 of the bar notches until the leveris swung horizontally to rotate the rod 26. The rotation of the rod 26will disengage the edge 29, of the bar 23, from the notches 27 and allowthe book rest to be swung downwardly into a vertical position. It willbe noted that by having a plurality oi notches 27 the book rest may besupported in an inclined position or in a horizontal position. As thebook rest is raised towards a horizontal position the wings 42 willswing open thereby allowing the book to open and be supported by thewings. As the book rest is lowered towards a vertical position theangular eX- tensions 4C5 engaging the curved or flared lips 19 willautomatically swing the wings to a closed position thereby closing thebook. The book is connected to the book rest by the rod which engagesbetween the leaves of the book and is tightened by the thumb nut on thethreaded portion 39. Should it be desired to entirely remove the rod 35the thumb nut 4.0 is removed and the right angle threaded extension 39is withdrawn through the opening 38. The rod may then be swung to bepushed through the lower opening 37. The enlarged end 86 on the lowerend of the said rod 35 prevents this end from being withdrawn throughthe opening 87. When the wings are swung into open horizontal positionthe plates 48 will engage the under edge of the book rest and limit theswinging movement of the wings as well. as furnish a support there-for.Should it be desired, for any reason, to disconnect the wings the samemay be raised against the tension of the springs l6. This will allow therod extensions A3 to be removed from the lowermost eyes 41 and then theupper extensions 44. may be lowered and withdrawn from the uppermosteyes. The coiled springs 46 also tend to normally properly position theextensions in the eyes and prevent accidental displacement thereof. Theprojections 16 on the rear face of the support 11, being verticallyspaced allow for a slight vertical adjustment of the support withrespect to the frame 3.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent is:
